Selective attachment processes in ancient gold

01/04/2014  The original gold winnowing process was a dry separation technique, accomplished by wrapping sandy gold ore in a woolen blanket, which was then shaken up and down by two men (Wilson, 1961). In the process, the gold particles were triboelectrically charged and attached to the blanket. Then, the blanket was opened, and the material was tossed into the air, causing the sand particles to blow

Mineral processing - Wikipedia

Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding ...
